Got it. Would you recommend first upgrading to 0.94.7 or can we directly go to jewel, according to the realease notes a direct upgrade should be possible. > > The biggest question though is why you're upgrading Ubuntu.

The reason for updating to 16.04 is that we dont want to use the odd system out(upstart vs systemd), we've been burned by ceph before suddenly not publishing packages for a system although it was still supported on paper so we rather use something more "mainstream".
